The 36-year-old San Francisco woman got into an argument with the suspect, a man she knows, and he stabbed her in the chest with a screwdriver, police spokesman Sgt. Michael Andraychak said.

Responding officers found the victim suffering from multiple stab wounds and a passerby was assisting the victim by administering first aid, Andraychak said.

The victim was taken to a hospital with injuries that were initially considered life-threatening. Police today said she is expected to survive. Officers arrested the suspect, Wilber Echeverria, 27, of San Francisco at the scene, Andraychak said.

They recovered the weapon from the victim’s car, which was parked nearby with the windows open.

Echeverria was arrested on suspicion of attempted murder, battery and domestic violence.
